To provide front hanging spectacles which eliminate the possibility of the dislodgment of auxiliary lenses and allow the removal of hooking means from the front hanging spectacles and the easy exchange thereof with another hooking means even when a person utilizing the spectacles detains the front hanging spectacles at the already worn spectacles already worn by this person.
Joint members 4 having the hook parts 41 detainable to the front parts of the already wearing spectacles F are freely attachably and detachably held between the auxiliary lenses 1 and front rims 2 enclosing and clasping the same. As a result, the transmission of the expanding stress of the hook parts as a twisting stress to the front rims which occurs with the conventional spectacles does not occur when expanding and deforming the hook parts to an outer side in order to detain the hook part to the front parts of the already worn spectacles and there is no possibility that the front rims are largely twisted and permanently deformed and that the auxiliary lenses are dislodged by the twist deformation.
